Hell Teacher: Jigoku Sensei Nube

Nueno Meisuke, better known as Nuubee, is an exorcist who also happens to be the teacher for a 5th grade class at Doumori Elementary. While he uses many various exorcism techniques, his main weapon is his left hand, the Demon's Hand, which has the power of a chaotic demon sealed within it.

The series follows Nuubee and Doumori Class 5-3 though the many weird, insane, and downright silly supernatural encounters they face.
